5 Simple (plant-based) Ways to Beat the Blues

Updated: Sep 8, 2021

Fall is a beautiful season: turning leaves, crisp air, finally being able to break out those boots—but, for some, it can also be a tough emotional season. The shorter, darker days may have you, or someone you know, feeling a little down—and while there are a wide variety of potential causes for feeling this way, and numerous paths that are available for treatment, there is some evidence that certain foods and nutrients can help to improve these feelings.

Studies show that following a plant-based diet, paired with regular exercise and mindfulness techniques, greatly improves general well-being and mood, and can even result in those previously diagnosed with depression to experience a full remission of their symptoms [1,2,3]. Following a strict vegan diet has also been shown to improve depression, anxiety, fatigue, social functioning, and mental health [2,3]. Self-reported mental health measures improved by 5% after 22 weeks of taking part in a vegan nutrition program [3]. In another study, after just 12 weeks of consuming a diet rich in plant-based protein, gluten free grains, nuts, seeds, fruits and vegetables, healthy oils, and natural sweeteners, only 7% percent of participants experienced no change in their mood, with 62% experiencing a large improvement [1].

More research needs to be done to determine the exact reasoning behind why specific foods improve mood, but the following are some spices and nutrients that have been studied, and have positive effects on mood.


Depressive symptoms improved following only eight weeks of adding this spice into the diet of teenagers (in the form of a supplement) [4].


Curcumin is turmeric’s active ingredient. Just six weeks of curcumin supplementation has been shown to result in a 62.5% positive response rate in mood [5].

An easy way to incorporate these spices into your diet is by adding them to your grains, like brown rice or quinoa.


Persistent negative mood is associated with increased inflammation. As an anti-inflammatory, this fatty acid may help to boost mood [6]. One tablespoon of ground flaxseed provides nearly 1600mg of omega-3, and two tablespoons of chia seeds has a whopping 4900mg [7]!

Vitamin B12

Vegans and vegetarians have a high likelihood of being deficient in this vitamin, but fortified nutritional yeast is a great source, and is easy to add into your diet [8]. Try sprinkling some over your veggies or adding it to your popcorn!

Vitamin D

Sun grown mushrooms are one of the few dietary sources of vitamin D besides fortified foods, and the vitamin D they contain is just as bio-available and effective as taking a supplement [9]. Look for mushrooms in the produce aisle packaged with a label indicating them as containing vitamin D.

What do you do to boost your mood when the days get shorter and temperature gets cooler?
